To protect the wild Pokémon being treated in the facility, a jamming signal prevents the use of empty Poké Balls throughout the island. However, in gameplay, this only applies in the battle against Nihilego. The player can use Poké Balls in Trainer battles normally (although they will be blocked by the Trainers, as usual).

Pokémon Sun and Moon

After assisting Faba in stopping two Team Skull Grunts from harassing a Slowpoke on Memorial Hill, the branch chief invites the player to Hano Grand Resort after they finish their grand trial with Olivia. Upon arriving at the resort with Hau, Faba will take them to Aether Paradise. The player and Hau are then introduced to Wicke, who gives them a tour of the facility. At the top floor, the player meets the President, Lusamine, who welcomes the two trial-goers and professes her love of Pokémon.

Later, after the player has defeated Team Skull at their base in Po Town, Lillie is revealed to have been taken away by Plumeria. Gladion later reveals that Lillie was taken to Aether Paradise, where the player, Hau, and Gladion start looking for her next. While raiding the facility, new details about Cosmog, the Ultra Beasts, and Type: Null are revealed. It also turns out that the Aether Foundation has been working together with Team Skull and sponsoring their criminal activities, forcing the player to battle their way through members of the evil team, including their Boss, Guzma.

In the big mansion at the end of Aether Paradise, the player finds Lillie, who is facing Lusamine, her mother, about Cosmog's fate. The player, Lillie, Hau, and Gladion follow Lusamine into her secret trophy room, where Lusamine reveals how she is intending to use Cosmog's power to open Ultra Wormholes all across Alola and summon multiple Ultra Beasts through them. As wormholes start opening and Ultra Beasts start emerging all over Alola, the player engages Lusamine in a battle. After Lusamine is defeated, she uses a specially designed Beast Ball to capture the Ultra Beast that emerged through the wormhole she had created inside the room, before both she and Guzma disappear into the fading wormhole themselves.

Pokémon Ultra Sun and Ultra Moon

In Ultra Sun and Ultra Moon, after the player has driven off the unidentified Pokémon that appeared from an Ultra Wormhole, Dulse and ZossieUS/Phyco and SolieraUM of the Ultra Recon Squad will appear and explain that the Pokémon was an Ultra Beast. Lusamine informs the player and Hau that the Ultra Recon Squad has been working with the Aether Foundation, providing them with information about the Ultra Beasts. The Ultra Recon Squad members also tell how they came from a world from which Necrozma had stolen all of its natural light. Afterwards, the player and Hau depart for Ula'ula Island.

During the player, Hau, and Gladion's search for Lillie in Aether Paradise, the player will encounter the Ultra Recon Squad again after defeating Guzma. After defeating them, the player will encounter Lusamine and Lillie and follow them to Lusamine's trophy room along with Gladion and Hau, where Lusamine explains that she intends to travel to Ultra Space and defeat Necrozma in order to keep the Alola region and its Pokémon safe from it. For this purpose, she needed Cosmog's power to open Ultra Wormholes. Although she makes clear that she hates Ultra Wormholes with every fiber of her being, them being what took her husband away from her, but she's still willing to go through one in order to protect Alola. Because of Gladion and Lillie's objections, Lusamine challenges the player to a battle, intending to show everyone she's capable of dealing with Necrozma. Despite being defeated, Lusamine still chooses to ignore her children, forcing Cosmog to open a wormhole which both she and Guzma disappear into.

After Lusamine's departure, the Ultra Recon Squad berate her selfish behavior, and tell everyone that the way to their world, Ultra Megalopolis, where Necrozma resides, is by using the power of the Legendary Pokémon of the sunUS/moonUM, which can appear at thealtar on Poni Island. The next day, Gladion gives Lillie the Moon FluteUS/Sun FluteUM, one of the items required to summon said Legendary Pokémon. Following this, Gladion takes the player and Lillie to Poni Island.

After the player has become the Champion, Aether Paradise is invaded by Team Rainbow Rocket in the middle of a live news broadcast. Using the power of an Ultra Wormhole, they transform Lusamine's mansion into Team Rocket's Castle, wherein they settle their base of actions. Lusamine tries to stop them, but ends up getting taken hostage. The player and Lillie head to the castle, intending to save Lusamine. On the way, they discover that Faba had actually assisted Team Rainbow Rocket in their takeover of the facility, intending to use their success to advance his own career. After the player and Lillie have defeated Faba and an Aether Foundation Employee in a Multi Battle, they enter the castle. Within the castle, the player must defeat various villainous team leaders summoned through Ultra Wormholes in order to advance further. After the player has defeated Giovanni, the leader of Team Rainbow Rocket, Colress uses his technology to restore the mansion back to its normal state, sending everyone back to the worlds they originally came from.

Once the player has defeated Gladion in a Title Defense battle at the Pokémon League, Lusamine's husband, Mohn, will appear in the entrance area. Due to suffering from amnesia as a result of going through an Ultra Wormhole, Mohn is unable to remember his marriage with Lusamine, which she chooses to not remind him of, simply being happy to see that Mohn is enjoying his life of running Poké Pelago.

1F: Entrance

The entrance has two service counters, one of which houses a PC and a healing spot in the form of an Aether Foundation Employee. This floor also provides the player access to the exterior portions of the facility, with one entrance to the front and one entrance to the back.

The back door is locked until the player defeats Faba and an Aether Foundation Employee in a Multi Battle, which can only be done after reading the notes in Secret Lab B. The player is not permitted to go out the front door until they battle Lusamine in the mansion.

After battling Gladion at Aether House, but before battling Lusamine, the ferry is not present. Instead, an Aether Foundation Employee stands out front of Gladion's Team Skull ship, which is moored on the east side, and will take the player to Malie City.

B2F: Lab area

The Lab area contains two laboratories, Secret Lab A and Secret Lab B. Secret Lab A contains secret files about the creation of Type: Null, as well as Faba's personal files, while Secret Lab B contains information about Cosmog and the Ultra Beasts.

In Pokémon Sun and Moon, after entering the Hall of Fame, Wicke can be found at Secret Lab B, providing the player with information about the Ultra Beasts they have caught.

In Pokémon Ultra Sun and Ultra Moon, the entrance to the hallway is locked before defeating Faba at 1F.

Pokémon

A Nihilego appears during the player's first visit, but cannot be captured. It has an aura that gives it +2 Defense stages and will flee on the fifth turn (if the battle has not already ended) unless it is trapped.

A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.

While Ash and his friends were dealing with Ditto, Team Rocket, who had been hired to work as Employees at the facility by Faba, kept trying to catch Nebby, and eventually ended up accidentally finding secret documents about Type: Null and the Ultra Beasts from Faba's personal laboratory.

In Mission: Total Recall!, Ash and Lillie were teleported into the Aether Paradise Lab area by Nebby. Faba, afraid that Lillie could be regaining her memories of the Nihilego attack and thus jeopardize his career, took her and attempted to erase her memories again with his Hypno. However, his plans were foiled by the appearance of Ash and Gladion. Although Ash was subdued by Faba's Hypno, Gladion was able to save Lillie when his Type: Null broke its confinement mask and became Silvally, then proceeding to defeat Faba's Pokémon. Amidst of all this, Lillie managed to recover her remaining suppressed memories, allowing her to completely get over her fear of touching Pokémon.

In Faba's Revenge!, Faba tricked Nebby into teleporting him into the Lab area, where he used a device to trap it and started using its power to open an Ultra Wormhole. Although Ash, Lillie, Gladion, and Lusamine appeared to stop him and free Nebby, the wormhole was still opened, allowing a Nihilego to pass through it. Lusamine, Gladion, and Ash attempted to battle against it, but it proved to be too powerful for their Pokémon to handle. The Ultra Beast then attempted to take Lillie with it, but even though Gladion tried to protect her, Lusamine ended up pushing Gladion aside at the last moment, causing her to get taken into the Ultra Wormhole by Nihilego instead, much to Lillie's horror.

Ash and Lillie visited Aether Paradise once more during Don't Ignore the Small Stufful!, when they were assigned to deliver Professor Burnet's lunch. Meanwhile, Team Rocket had gotten jobs once again at Aether Paradise and started plotting to steal the Pokémon. However, a Stufful suddenly started following them around before grabbing a hold of Jessie's hair. They were soon confronted and accused of stealing Stufful, only for Bewear to show up. Bewear recognized Stufful as its own child and took it home with her and the trio.

It officially debuted in Unleashing the Incredible Z-Move, where an Aether Foundation Employee recorded footage for another commercial with the assistance of several Alolan people. Afterward, the Employee was greeted by Lusamine, who looked forward to seeing the commercial when it was completed.

Later, it was revealed that Aether Paradise was built on top of an island owned by Sun's great-grandfather. The island was given to Sun's great-grandfather by a member of the Aether Foundation so he could fulfill his dream of creating the Poké Pelago. After the man passed away, the island was taken back by the Aether Foundation.
